Ototoxicity with both auditory and vestibulatory effects is the most serious of the adverse reactions of aminogycosides as it is mostly irreversible. Vestibular involvement manifests itself by dizziness, nystagmus, vertigo and ataxia. Cochlear toxicity results initially in high-frequency hearing loss. Amikacin more often causes cochlear damage than vestibular problems, while gentamicin and tobramycin are associated more frequently with vestibular symptoms. 

Neurotoxicity including high-frequency hearing loss, has been reported. 

Organic solvents are ototoxic (23) and can cause vestibular damage and extracochlear high-frequency hearing loss (24). Ototoxic solvents include carbon disulfide, n-hex-ane, styrene, toluene, and trichloroethylene, and xylene (25,26). 

There is a discrepancy between clinical observations, in which very few patients receiving aminoglycosides actually complain of hearing loss, and the reported incidences of ototoxicity in studies of audiometric thresholds. A major reason for this discrepancy relates to the fact that aminoglycosides cause high-frequency hearing loss well before they affect the speech frequency range in which they can be detected by the patient (21). 

Extensive serial audiological studies in an HIV-infected child showed high-frequency hearing loss after 19 months of combined treatment with zidovudine and didanosine (dosages unknown), which were started at 24 months of age (9). Normal tympanograms indicated that this hearing loss was sensorineural. 

During their tour in the White House, two presidents had hearing aids fitted because of high frequency hearing loss Bill Clinton and Ronald Reagan. 

High frequency hearing loss is a type of hearing loss which involves a person s inability to hear clearly speeches containing high frequency components. As an example, a person with such inability will face problem to understand...

To simulate the sound that can be heard by the high frequency hearing loss individuals, the acquired input signal... 

In this work, we afforded a method that used the nonlinear frequency compression to improve the speech inteliigi-bility for the person with high frequency hearing loss. After... 

In short, it can be concluded that the proposed method is able to improve the speech intelligibility for the hearing impaired person with high frequency hearing loss.
